Parsley dropwort is a weed which causes problems where it grows. At present, it grows mainly only in Northland and a few other locations within New Zealand. It is becoming more common in Auckland, Coromandel and Waikato. Parsley dropwort is a perennial weed, and it is troublesome because it is not readily eaten by animals due to chemicals present within the leaves.
Identify the problem
Parely dropwort is a hairless, parsley-like perennial with feathery leaves and an efflorescence white flowers on along stalk. It produces tubers at the end of its fibrous roots.
